Pin Terminal Slip Ring

The PST X Series is developed specifically for the packaging industries and is mostly used by flow pack machines. The slip rings allow high current circuits, combined with signals for sensors, and are suited for high operation speed with a long lifetime. The terminals pins are connected on the slip ring, allowing a smooth installation.

PST-X32 has 2 or 3 high currents circuits and can be combined with two circuits for sensors. The PST X32 is also available in an IP65 version, suitable for machines that need regular cleaning with water. The PST-X45 Series has 6 power circuits and a model with additional 2 circuits for signals. Their compact size and connectors allows for quick installation even into small systems, maintaining high reliability and performance.

Electrical Slip Ring with Integrated Air/Water Swivel

Penlink can design a specialized solution intended to be seamlessly integrated to your assembly system. We are experts in helping our customers defining and executing the design of the rotary interface.

Many automation lines have a need for transfer of different media – not just electricity. Often the case is that space is limited, and temperatures and rotational speeds are outside normal boundaries. To achieve the best possible solution for the customer, slip rings and rotary unions of different medias are combined within a compact unit in order to save space and facilitate easy installation.

The optimal design of every rotary unit is different. Penlink can achieve this and still hit the cost efficiency sweet spot, which is why we have so many successfully projects within the assembly line industry.

Power and Pressure in a Small Package

By combining a hydraulic rotary union for pressurized media with a slip ring, the whole system can be reduced in size. Due to the swivel being carefully designed into the slip rings hollow shaft. This makes for a great solution with reduced costs.

Our hydraulic unions can be design with multiple passages, and up to 2,5” passages for 350 Bar hydraulic pressure with x1,5 test pressure. The combined slip ring solution can transfer up to 1GB data or video and be used for remote control of any automation system.

We understand that not all of our standard products will integrate directly into your equipment. We have designed them to be as universal as possible but sometimes that just isn't enough. We will work fast to find a solution that better suits your mounting and connection needs.

Applications with very tight or unique size constraints are often limited on the selection of rotary union options available - therefore, require some form of modification. Regardless of the scale of complexity of a change, we will work side-by-side with your team to deliver a product that fits your exact requirements.

Integration of a Swivel & Slip Ring is a smart solution to increase productivity!

Little more in depth: Plastic Blow Molding

We can offer blow extrusion rotary unions that is designed to maintain low friction plating on shaft sealing surface, which reduces heat and extend the life of the application.

This means that the production can move forward without any unnecessary stops. What is also great about this solution is that we can make it a direct replacement to existing designs in the application. The swivel does not need any lubricant and has low friction seals for high demand duty cycles.

Integrate this swivel with a slip ring and you have a solid solution for plastic blow molding that transfer hydraulic pressure, power, data and signals

  • Your Needs
    Long life. Unique product for air, oil & water. High pressure.
  • Our Solution
    Low friction plating on shaft sealing surface to reduce heat and extend the life. Low friction seal for high demand duty cycle. No lubrication required. Pressures up to 517 BAR.
  • Your Needs
    No leakage. High temperature (100°C). Electric rotary joint integration.
  • Our Solution
